“…As can be seen from the table, the proposed antenna is slightly larger than those of other antennas, but the large size is the common drawback of monopole antennas. Although the antenna in has a larger impedance bandwidth than the proposed design, the AR bandwidth is relative narrow, leading to a narrow overlapping bandwidth for use. In contrast, the proposed antenna has both wide impedance and AR bandwidths, which are the competitive advantages over other antennas.…”

“…In Reference , a C‐shaped monopole antenna obtained a 65.2% AR bandwidth by loading a square loop and an adjusting stub on the ground plane. In Reference , a CPW‐fed rectangular patch shaped monopole achieved CP radiation with 63.3% AR bandwidth by using an asymmetric ground plane of different heights in addition with loading a parasitic square loop. Although the antennas achieved wide AR bandwidth, the geometry structures are a little complicated.…”

A simple printed monopole antenna using parasitic loops and defective ground plane is presented for broadband circular polarized (CP) radiation. For this purpose, two square open loops, which install air gaps at the corner and close to the monopole, are printed on both sides for achieving broadband CP radiation with three minimum axial ratio (AR) points. By using a defective ground plane with a vertical slot and a horizontal slot, additional AR points can be excited to further broaden the AR bandwidth. This design was fabricated, and the measured results show that the antenna with a simple structure achieves both wide impedance bandwidth of 87.2% (2.62‐6.67 GHz) and AR bandwidth of 83.9% (2.6‐6.36 GHz).

“…In Reference , a T‐shaped slot is created on the ground and an X‐shaped slot is etched on an annular monopole to achieve 4.02%, 4.51%, 1%, and 12.74% bandwidths. In References 12 and 13, a technique of using an open loop parasitic element along with a modified monopole produced wideband CP results of 65.2% and 63.3%, respectively. Some of these designs have relatively smaller axial ratio (AR) bandwidths or suffer from design and fabrication complexities.…”

This article presents a novel planar monopole antenna with circular polarization. The 3‐dB axial ratio (AR) is achieved by: shifting a vertical monopole to the left edge of the substrate in conjunction with a laterally inverted L‐shaped ground plane. When viewed from the top, the antenna resembles an uneven T‐shaped structure rotated at 90°. Measurement results show that; a 3‐dB AR bandwidth is achieved from 3.1 to 6.2 GHz (66.7% fractional bandwidth) and an S11 ≤ −10 dB bandwidth is realized from 2.5 to 6.5 GHz (88.9% fractional bandwidth). The proposed antenna is compact with an area of 20 mm2, produces stable radiation patterns, and its simple to design and fabricate without using parasitic elements or introducing slots on the antenna.

“…The study of gain enhancement is done using a U-shaped ground plane to enhance the capacitive coupling and directivity and also to reduce the size of the antenna. In a CPWfed CP monopole antenna [17], the CP is initially achieved by utilizing the asymmetric ground, and then a rectangular open loop is introduced to obtain wide-impedance bandwidth and broadband circular polarization characteristics. In [18], a CPW-fed dual-band and dual-sense monopole CP antenna has two rectangular parasitic elements and an I-shape grounded stub to achieve the desired circular polarization characteristics.…”

Abstract-In this paper, a compact, circularly polarized printed monopole antenna is proposed at ISM band (2.4-2.48 GHz) for biotelemetry and implantable applications. The proposed antenna possesses a small dimension (10 × 10 × 0.3 mm 3 ) and simple microstrip feeding structure. The circular polarization is easily achieved by introducing an "L" shape stub at the ground plane in ISM. The simulated 10 dB impedance bandwidth is around 13.87%, and 3 dB AR bandwidth is around 5.3%. The effect of different body phantoms is discussed to evaluate the sensitivity of the proposed antenna. The simulated peak gain of the proposed antenna is about −7.79 dBi across the operating band. The SAR analysis of the antenna configuration has also been studied.
